Squarcle (Skw-air-kol) Chess, or Chess on the Surface of a Cone

By Christian Hupp

Squarcle Chess is so called because it is the combination of a square board (SQUARe) and a circular board (cirCLE).

Think of it as a series of nested Monopoly™ boards. The centermost board is 4 squares in size, the next one is 12 squares in size, the next is 20, and so on and on.

There are two types of Squarcle Chess: 10X10 Squarcle Chess, and 8X8 Squarcle Chess. Both will be displayed simultaneously, and I will mark off parts that only pertain to one variant or the other.

The the reason this variant could also be called chess onthe surface of a cone becomes apparent when you see the board:


Below is shown the starting positions of the 10X10 version of Squarcle Chess. There are a total of fifty pieces:1 White king, 1 Black king, 1 White queen, 1 Black queen, 1 white Count, 1 Black count, 2 White ballistas, 2 Black ballistas, 2 White trebuchets, 2 Black trebuchets, 2 White Rooks, 2 Black Rooks, 2 White rabbits, 2 Black rabbits, 2 White knights, 2 Black knights, 2 White bishops, 2 Black bishops, 10 White pawns, and 10 Black pawns. There are 25 pieces per player.

As always, the right-most square closest to you is white.

The diagram below shows the starting positions of 8X8 Squarcle Chess. Notice how familiar it looks. There are 16 pieces per player (totaling 32 pieces):1 king, 1 queen, 2 bishops, 2 knights, 2 rooks, and 8 pawns. Like the board above, the right-hand, closest square is white.

In this game, one special provision mut be made before I continue. It is a rule that already exists in FIDE chess, although it is a bit redundant in normal chess. The rule is as follows: no piece may move in such a way that the board looks no different at the end of the turn then it did at the beginning. This prevents people from being able to simply pass a turn.

All the pieces exist in both versions of squarcle chess, with the exception of the pieces marked.
